Question

Which of these will change if the air in a
closed bottle is heated?
A
B
C
D
the mass of the air
the composition of the air
the air pressure in the bottle
the number of air molecules in the bottle​

Answer 1

Answer:

The air pressure in the bottle will change.

Explanation:

According to Gay-Lussac's Law, one of the main gas laws, the pressure of gas is directly proportional to the temperature of the gas. This means that as the temperature of the gas increases, the pressure of the gas will increase as well. Therefore, if you heat a closed bottle, the air pressure inside the bottle will change (increase).
